Verified step by step guidance
1
Identify the molecular formula given: CH\3F.
Recognize that the subscript numbers indicate the number of atoms of each element in one molecule.
In CH\3F, the subscript 3 after C and H means there are 3 hydrogen atoms, 1 carbon atom (no subscript means one), and 1 fluorine atom (no subscript means one).
Since there is no subscript after F, it means there is exactly 1 fluorine atom in one molecule of CH\3F.
Therefore, the number of fluorine atoms in one molecule of CH\3F is 1.
